Application filed August 24, 1914. Seria1 No.-85 8,318.

To all whom it'may concern."

Be it known that I, FLOYD N. ALBERTSQN, a citizen of the United States, residing at Brooklyn, in the county of .Kings and State of New York, have invented certain new and useful. Improvements in Fluid-Gages for Gasolene-Tanks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Thisinvention comprehends certain new and useful improvements in fluid gages and has for its primary object to'provide a device of this character which will beof such construction that-it may be especially adapted for use in connection with gasolene tanks on motor vehicles and the like to indicate the amount of gasolene in said tank.

The invention has for another objectto provide a device of this character which will be of extremely simple construction and operation as well as highly efiiclent m use and which will include mechanism operated by movement of a float positioned upon guides in the tank, movement of the float upon the guides serving to control the position of a rotary indicating dial before a glass.

The invention has for a further object to generally improve and simplify the condevices of this character and increase the efliciency thereof without materially increasing the cost of the same.

With these and other objects in new as .will become more apparent as the description proceeds, the invention consists in certain novel features of construction, comblnation and arrangement of parts as will be hereinafter more fully described and laimed. 1 I

For a complete nderstandmg of my invention, feference is to be had to the following desciiption and accompanying drawings, in wliich Figure 1 is a diagrammatlc new of the invention in use, portions of an automobile being shown in section, Fig. 2 is a rear elevation of the tank with a portion of the to disclose the float mounted upon the guides in said tank, 3 is a fragmentary elevation, showing the dial and cap within which the same is po-x.

sitioned upon the dash-board, Fig. l is a detail vertical section on rection;

the plane of line l& of Fig. 3, Fig.- 5 a detail vertical sec tion on the plane of line 5-5 of Fig. 4, and

6 is adetail elevation of the rotary Referring in detail to the drawings by numerals, designates a gasolene tank of a motor vehicle or the like and within which is placed a pair of parallel vertically extend-- ing guide rods 2 secured in position in the tank in any suitable manner and having a float 3 formed 'ofcork or thelikeimounted for movement upon said guide rods, suitable protecting sleeves 4; being positioned in the openings of the float 3 and engaged around the guide rods 2 to prevent wearing of the float 3 during its movement upon said guide rods 2 as the amount of gasolene in the tank 1 increases or decreases. Depending from the float 3 is a cord .5 which extends through the bottom of the gasolene tank 1 between the guide rods 2 and extends along the interior of the guide tube 6 which has one end secured to the bottom of the gasolene cord 5 is connected at its forward end to a sprocket chain 11 which is engaged over a sprocket wheel l'2-mounted upon the shaft 9 and has a weight 13 mounted upon its opposite end and slidably engaged in a' weig it inclosing and guiding-tube 14: which depen s from the casing 7 and is preferably positioned parallel with the upper vertical portion of the tube 6, said tube 14 being connected with the casing 7 in any suitable manner, such as shownat l5.

It will be understood that as the contents of the gasolene supply tank 1 is consumed and the float 3 moved downwardly in said tank 1, the weight 13 will also move downwardly to take up the slack in the sprocket chain 11 and cord 5, thereby rotating the sprocket wheels 12 and shaft 9 in one di- As the tank 1 is again filled and the, level of the contents rises, the float 3 will-also rise and pull upon the cord 5 and chain 11, thereby raising the weight 13 and rotating the sprocket wheel 12 and shaft 9 in-the reverse direction. The shaft 9 also has a gear wheel 16 mounted thereon and engaged with the gear wheel 17 carried by rotatedupon rotation of the shaft 9, but in a reversedirection; It will therefore be seen that as the float 3 and weight 13 move downwardly upona decrease of theiquantity of gasolenein the tank 1, the indicating dial 18 carried by thfe shaft 10 will be rotated: tof bring the colored portion 19 thereof before. the transparent portion 20. I

of the plate. 21, positionedin the indicator top 22 formingthe frontof the indicator casing 7.

It will be understoodthat the colored 51 tion 19 of the dial 18'is preferably red, but may be any other color desired and when-the tank l is filled only the white or uncolored portion of the disk 18 may beseen before the transparent portion 20 of the-plate 21. It will'be understood that the'transparent por tion of the plate 21 is preferably-formed of glass, but may be of any suitable material andthe plate 21 may be held against the. casmg 'bin. any suitable manner toform an air -,'tight connection between said plate 21 and easing 7 .1 The casing 7 may then be inserted throughthe dash-board 26 and the cap 22 secured upon said casing 7, said cap 22 havingia circular flange 23 projecting from'one. ,eaaand provided with interior threads for 'enga'gementwith the threaded portion 24 of" the casing 7 which is engaged through the opening 25 in the dash board26 as previously mentioned or through any'other desired portion of the vehicle. It will be understood that the tubes 6 and-14 are positioned against one face of the portionof the vehicle through which the casing 7 is engaged, While the remaining portion of the cap 22 is engaged againstthe opposite face of said portion of the'vehicle, as clearly shown in the-drawings, thereby securely holding the casing 7 in position without the :use of screws or other securing members.

It willbe understood that the cap 22 has suitablejindicating characters 27 formed on "one face around the transparent portion 20 of the plate,21, by means of which the amount of gasolene in the tank 1 may be readily determined. by the position of the first edge fof the colored portion 19 of the 1 8. It vwill further be evident that transparent portion -20 of the plate 21, the tank lis entirely empty.

From the foregoing, it will be readily apparent that this gage will work under pressure, and may be readily applied to pressure tanks, as well as gravity tanks.

. While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in the details of construction, combination, and arrangement of parts may bemade without departing from thte spirit and scope of the invention as claimed or sacrificing any of the advantages thereof.

What is claimed is A gage comprisinga casing. an indicating disk mounted upon ashaft positioned transversely'through the casing, a sub shaft positioned beneath the first mentioned shaft and'disposed within the casing, gears connected respectively centrallyto the first mentioned shaft and on the end of the last mentioned shaft, said gears meshing with one another, a second gear secured centrally to the last mentioned shaft, a pair of cylindrical pipes connected to the under surface of said casing a spaced distance apart and communicating directly with the interior thereof, a flexible connection mounted over the last mentioned gear and meshing with the same and its opposite ends extending intoface of said float, said cord connected to one end of the flexible connection, the opposite end ofsaid flexible connection havlng a weight thereon, said weight adapted to cause of the weight downwardly upon the decrease of the liquid within the tank.

In testimony whereof I aflix my signature in presence of'two'witnesses.
